Question

我正在尝试配置MF容器以使用Cloudant。并通过数据代理从移动应用程序查询模糊。

我按照说明在容器上配置数据代理： http://www-01.ibm.com/support/knowledgecenter/?lang=en#!/SSHS8R_7.1.0/com.ibm.worklight.deploy.doc/deploy/t_configure_data_proxy.html
我将文件/ibm-mfpf-container-7.1.0.0-eval/mfpf-server/usr/env/server.env配置为具有以下值：
```
publicKeyServerUrl=HTTP_CONTAINER_PUBLIC_IP_PORT/MF_PROJECT_CONTEXT_ROOT
```

文件/ibm-mfpf-container-7.1.0.0-eval/mfpf-server/usr/config/dataproxy.xml具有以下值：

     <!-- Declare the JNDI properties for the MobileFirst Data Proxy.

                Also, uncomment the entry publicKeyServerUrl in server.env and fill in the correct URL.
     <jndiEntry jndiName="datastore/CloudantProxyDbAccount" value='"hostname"'/>
     <jndiEntry jndiName="datastore/CloudantProtocol" value='"http"'/>
     <jndiEntry jndiName="datastore/CloudantPort" value='"80"'/>
     <jndiEntry jndiName="datastore/CloudantProxyDbAccountUser" value='"cloudantuser"'/>
     <jndiEntry jndiName="datastore/CloudantProxyDbAccountPassword" value='"cloudantpassword"'/>
     -->
</server>

然后我运行了脚本prepareserver并启动服务器。
当我打开http://CONTAINER_PUBLIC_IP:9080/datastore时，我得到以下回复，这似乎很好： {＆＃34; imfdata＆＃34;：＆＃34; OK＆＃34;＆＃34;版本＆＃34;：＆＃34; 1.0＆＃34;}
我在这个容器上运行了bluelist示例，但我无法让它运行。它抛出以下异常：

2015-10-08 00：05：34.055 bluelist-objective-c [37850：708865] ***由于未被捕获的异常终止应用程序＆＃39;来自代理的致命异常＆＃39;，原因：＆＃39;无法创建远程数据库todosdb。错误：错误域= NSURLErrorDomain代码= -1001＆＃34;请求超时。＆＃34; UserInfo = {NSUnderlyingError = 0x7fcf72e6efa0 {错误域= kCFErrorDomainCFNetwork代码= -1001＆＃34;请求超时。＆＃34; UserInfo = {NSErrorFailingURLStringKey = IP_PF_CONTAINER：9080 / datastore / api / v1 / apps / default / todosdb，NSErrorFailingURLKey = IP_PF_CONTAINER：9080 / datastore / api / v1 / apps / default / todosdb，_kCFStreamErrorCodeKey = -2102，_kCFStreamErrorDomainKey = 4，NSLocalizedDescription =请求超时。}}，NSErrorFailingURLStringKey = HTTP_CONTAINER_PUBLIC_IP_PORT / datastore / api / v1 / apps / default / todosdb，NSErrorFailingURLKey = http://134.168.13.219:9080/datastore/api/v1/apps/default/todosdb，_ kCFStreamErrorDomainKey = 4，_kCFStreamErrorCodeKey = -2102，NSLocalizedDescription =请求超时。}＆＃39;

这是从运行此代码的iPhone simultator抛出的：

[manager remoteStore:dbname completionHandler:^(CDTStore *store, NSError *error) {...

我已将Objective C代码中的cloudantProxyURL设置为以下内容：
```
CONTAINER_PUBLIC_IP:9080/MF_PROJECT_CONTEXT_ROOT
```

知道问题出在哪里？我想在没有安全的情况下进行故障排除。我可以通过IMFDataManager API和数据代理对Cloudant进行未经身份验证的调用吗？或者用户必须进行身份验证？

===============

我可以在调用[manager remoteStore]之前通过调用适配器来强制执行身份验证，并且身份验证成功。我仍然得到一个错误当我运行以下代码连接到Cloudant上的数据库并从中查询时。 [manager remoteStore]是抛出错误的那个：

IMFDataManager * manager = [IMFDataManager initializeWithUrl：@＆＃34; HTTP_HOST_PORT / datastore＆＃34;];

// Get reference to data manager
//manager = [IMFDataManager sharedInstance];

NSString *dbname = @"orders_db";

// Create remote store
[manager remoteStore:dbname completionHandler:^(CDTStore *store, NSError *error) {
    if(error){
        // Handle error
         NSLog(@"Error: %@ %@", error, [error userInfo]);
    }else{
        CDTStore *remotedatastore = store;
        NSLog(@"Successfully created store");
    }
}];

我收到此错误：

2015-10-09 02：14：39.029 bluelist-objective-c [2655：52223]错误：错误域= NSURLErrorDomain代码= -1012＆＃34;（null）＆＃34; UserInfo = {NSErrorFailingURLStringKey = http://134.168.13.219:9080/datastore/api/v1/apps/default/orders_db，NSUnderlyingError = 0x7fa270c27270 {Error Domain = kCFErrorDomainCFNetwork Code = -1012＆＃34;（null）＆＃34; UserInfo = {_ kCFURLErrorAuthFailedResponseKey = {url = http://134.168.13.219:9080/datastore/api/v1/apps/default/orders_db}}}，NSErrorFailingURLKey = http://134.168.13.219:9080/datastore/api/v1/apps/default/orders_db} { NSErrorFailingURLKey =＆＃34; http://134.168.13.219:9080/datastore/api/v1/apps/default/orders_db＆＃34 ;; NSErrorFailingURLStringKey =＆＃34; http://134.168.13.219:9080/datastore/api/v1/apps/default/orders_db＆＃34 ;; NSUnderlyingError =＆＃34;错误域= kCFErrorDomainCFNetwork代码= -1012 \＆＃34;（null）\＆＃34; UserInfo = {_ kCFURLErrorAuthFailedResponseKey = {url = http://134.168.13.219:9080/datastore/api/v1/apps/default/orders_db}}＆＃34 ;; }

另一点，当我使用SSH登录容器并在/opt/ibm/wlp/usr/servers/worklight/server.xml中显示server.xml时，我找不到添加OAuth TAI的行。根本没有。

Answer 1

上述异常表示访问数据代理组件的授权不成功。

是否可以修改dataproxy.xml以提供正确的securedUrls参数。 securedURL的值应为“/ datastore / *”而不是“datastore”。更新的代码段位于：

<usr_OAuthTAI cacheSize="1000" id="myOAuthTAI">
    <securityConstraint httpMethods="All" securedURLs="/datastore/*" scope="cloudant"/>
</usr_OAuthTAI>

让我知道dataproxy是否可以正常使用。

无法在Bluemix
